14*2 = 28 - 8 = 20,
20*2 = 40 - 8 = 32,
32*2 = 64 - 8 = 56.
20*2 = 40 - 8 = 32,
32*2 = 64 - 8 = 56.

14 * 2 = 28,
(14 + 6) * 2 = 40,
(20 + 12) * 2 = 64,
(32 + 24) * 2 = 122.
(14 + 6) * 2 = 40,
(20 + 12) * 2 = 64,
(32 + 24) * 2 = 122.

14+6 = 20.
20+(6*2) = 32.
32+24 = 56.
20+(6*2) = 32.
32+24 = 56.
